Quick Notes: Replacing Electrolytic Capacitors and Soldering

For now, here’s a short summary on troubleshooting techniques for the experienced hobbyist concerning (aluminum) electrolytic capacitors.

If you are restoring older electronic devices such as radios, tape recorders, ste- reos, power supplies, signal generators, etc., you should most likely replace all the electrolytic capacitors with the same (or sometimes larger) capacitance and voltage rating. For example, if there is a 100 μf, 10-volt electrolytic capacitor that has lost its capacitance or became leaky, you can replace it with a new 100 μf, 16-volt version. Of … Read the rest
